http://scpsandbox2.wikidot.com/legion122 last tab. feedback and input greatly appreciated. I've been working on this on and off for about a month or so, and would really like to know what I can do to improve it and make it just genuinely interesting.

This feels incomplete to me. I'm all for an extension of Orion's escapade into the thing beneath the shack, but having her essentially go down a hole, get trapped, and starve to death is a bit of a letdown.

Getting past what you already know, you could put in some origin story behind the thing in the yard. Maybe aliens. Or alternate realities' versions of the people that got trapped. I don't know.

I'll see what I can do about expanding on it. I was considering making this a multi-part series, but now I'm thinking it might be easier to just have a longer story all in one? Maybe? Either way I'll add to this.

You're hitting all of my Myst nostalgia buttons here, so I'd find this really hard not to upvote even if I didn't also like what you're doing here. This is totally what I would do if I found myself in 2508: start poking at things to figure out what made it all work. You've literally got nothing better to do, after all; it's that or yet another afternoon of debating philosophy with the tree that kind of looks like a person (and not that I'd say it to his face, but he's not entirely sane these days, which makes most of those end with us screaming at each other.)
